Your requirements could not be resolved to an installable set of packages.
Problem 1
- phpspec/phpspec[7.3.0, ..., 7.4.x-dev] require php ^7.3 || 8.0.* || 8.1.* || 8.2.* -> your php version (8.3.0-dev) does not satisfy that requirement.
- Root composer.json requires phpspec/phpspec ^7.3 -> satisfiable by phpspec/phpspec[7.3.0, 7.4.0, 7.4.x-dev].
